MIDDLINGS-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 332,616, dated December 15, 1885.

Application filed April 10, 1884. Renewed September 15, 1885. Serial No. 177,202. (No model.)

To all whom it may concern:

Be itknown that 1, WILLIAM KLOSIERMANN,

' of Young America, in the county of Carver This invention relates to certain new and use- 7 ful improvements in middlings-purifiers; and

it consists in improvements in the middlingspurifier for which Letters Patent No. 267,226 were issued to me on the 7th day of November, 1882.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal sectional elevation of my improved middlings-purifier. Fig. 2 is a rear end view of the same. Fig. 3 is an enlarged cross-sectional elevation of the same on the line a m, Fig. 1. Fig. 4 is a partial side View of the revolving drum, parts being broken out. Fig. 5 is a crosssectional elevation on the line yy, Fig. 1. Fig. 6 is a longitudinal sectional elevation of the front end of the same.

The shaft A is journaled horizontally in a frame, 13, to which side and end boards are secured to form a casing, and on the shaft are mounted two wheels, 0 G, on which a polygonal drum, D, is secured, which has an open end, E, the drum being supported clear from the shaft from the end E to the wheel or frame 0. On the end ofthe shaft A is mounted a sprocket-wheel, A, over which a chain, A passes, which also passes over a sprocketwheel, F, mounted on a horizontal shaft, F, arranged below the drum and parallel with the shaft A, which shaft is provided at the opposite end with a beveled cog-wheel, F engaging with a cog-wheel, G, mounted on a transverse horizontal shaft, G, provided at the ends with belt-pulleys H and H. A bevel cog-wheel, I, mounted on the shaft G, engages with the bevel-pinion I, mounted on a shaft, J, on the end of which a wheel, J, or a crank,

is formed, to which a connecting-rod, K, is

pivoted. The polygonal drum D consists of an outer shell secured on a series of longitudinal flat strips, d, and between the strips a series of longitudinal ribs, D, made of sheet metal, project from the inner surface of the sides, the said strips D being inclined in different directions. A middlings-distributing box, L, is secured in the drum D, and is secured at one end to a cross-piece, Z, secured to the frame B. The said middlingsdistribut ing box extends from the end E of the drum to within a short distance of the wheel or frame 0. The middlings-distributing box L has a pentagonal cross-section, the top being peaked, as shown, the sides being inclined toward each other and the bottom being horizontal. One or two screens, M, are arranged horizontally in the box a short distance from the top, and extend from front to rear. Below the screens a channel, 0, is formed, which hasa peaked top, and has a series of longitudinal slots, 0, in its inclined sides. At the rear end of the machine an air-conducting pipe or channel, P, leads into the channel O. The sides of the middlingsdistributing box L are provided with a series of longitudinal slots, L. Two longitudinal shafts, Q, are journalcd in the middlingsdistributing box--one at each side-and to the said shafts wings Q are fastened. On the rear end of the machine an elbow-lever, Q", is mounted on one shaft Q, which elbow-lever is connected by the bar K with the disk or crank J on the shaft J, and

by the bar K with a crank on the other I shaft Q, so that by the revolution of the shaft J the shafts Q, and the wings Q on the vsame will be rocked vertically. At the sides of the channel 0 slots or o enin s L are formed in the bottom of the middlings-distributing box. Longitudinal slots L are formed near the lower edges ofthe inclined sides of the top of the middlings-distributing box, through which slots the middlings can pass into the box. On the up! per surface of the inclined sides of the top ofthe middlings distributing box a series of riffles or ribs, R, are held,their lower ends being pivoted at R to the outer surface of the inclined sides of the top of the distributing-box, and their upper ends being pivoted to a bar, R which is peaked and fits on the top edge of the peaked top of the middlings-distributing box, and is adapted to slide on the same. A rod, S, provided with a handle-knob, S, projects from the sliding bar B through the rear end plate,

longitudinal opening or slot.

T, of the middlings-distributing box L into the chamber N, which end p'iece,T, fits in the N with the upper part of the middlings-dis tributing box. U is a chute for feeding the middlings to the purifier.

The fans are operated by a shaft, m, pro- Vided with a belt-pulley, it, over which a belt, 0, passes, which also passes over the pulley H on the shaft G. That part of the drum between the wheels or frame 0 and O is provided with a series of openings, over each of which bolting-cloth b is secured,and to the outer sides of the longitudinal ribs d of the polygonal drum metal plates 9- are fastened, the said plates being fastened at one longi; tudinal edge of the rib d, but the opposite longitudinal edge being held a short distance from the opposite rib d, so as to form a Between the sides provided with the apertures and the plates 1 swinging plates h are held, which are.

secured to those ribs d above which the free ends of the plates 9 are held, asis shown in Fig. 5. A shaft, j, projects inwardv from the cross-piece of the frame, and on the same an angle-lever, k, is pivoted, to the downwardlyprojecting arm of which a brush, 1", is secured, and to the horizontal arm an adjustable weight, 8, is secured,which presses the brush r against the bolting-cloth. I

The operation is as follows: The drum D is revolved, but the distributing-box remains sta tionary. The middlings are fed into the drum 1) through the chute U, and are carried by the ribs D upward and drop upon the two sides of the inclined or peaked top of the distributing-box as the ribs D are inclined in different directions, so that some discharge when the corresponding sides descend, and some discharge when the corresponding sides ascend. The middlings slide down the riffles or ribs running on the sides of the peaked top, pass through the slots Linto the box L,are thrown about by thewings Qon the rocking shafts Q, and finally drop through the slots L in the bottom of the box on the drum D, are again carried upward, and so on. The air is forced through the slots 0 in the air-conductor O, and this air carries the light particles upward and off through the screens M, and they are then carried off by the suction-fan, the windforcing fan and the suction-fan operating together. Some of the middlings also pass through the longitudinal slots L and drop upon the sides of the drum. If the knob S is pushed inward, the ribs R will stand almost at right angles to the slots L in the plane of theinclined sides of the top of the middlingsdistributing box. The middlings then slide down the said ribs very rapidly. If at any time it is desired that the middlings shall not Slide so rapidly, the knob S is pulled outward more'or less, whereby the ribs Rare inclined more or less, as shown in dotted' l nes in Fig. 4'that is, the speed at which the middlings'pass through the purifier can easily be regulated. The clean middlings pass from the end of the distributing-box into that part of the drum between the frames O and G and drop upon the pivoted plates or wings h, which are inclined from the frame G- to the frame 0, as shown in Fig. 6. The middlings pass through the bolting-cloth b, and

those parts of the gates or plates h near the;

frame or wheel 0; but the heavier particles. slide down the inclined gates it toward the. wheel or frame 0, so that the middlings are; thus separated automatically,according to the size of the particles. 1

In the chamber N a sliding'gate, w, is pro -v vided, which'can be opened to reach the knob,

S, and it can also be used to regulatethe power of the suction-fan.

Having thus described my invention,what I. claim as new, and desire to secure by Letters 7 Patent, is-

1. In a middlingspurifier, the combination,
